- Will 5G impact my health?
We’re excited about the benefits that our 5G network will bring for customers and businesses, but we understand there are some questions being asked about the impact on our health.
The WHO and the International Telecommunication Union (ITU) recommend that governments adopt the radio-frequency exposure limits developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
In the UK, the Government has adopted these exposure limits developed by ICNIRP and mobile network operators are required to operate within these guidelines.
